‘WHO recommended disinfectant formulations can be prepared quickly and easily by pharmacies and help ease the current shortage of disinfectants during the COVID-19 pandemic.

The researchers exposed Sars-Cov-2 viruses for 30 seconds to the WHO-recommended disinfectant formulations. "This time frame was chosen based on recommendations for hand disinfectants," says Stephanie Pfänder. Subsequently, the team tested the viruses in cell culture assays and analyzed how many viruses remained infectious. "We showed that both WHO-recommended formulations sufficiently inactivate the virus after 30 seconds," as Stephanie Pfänder sums up the results. Plus, this does not merely apply to the WHO solutions; rather, their main components, the alcohols ethanol, and isopropanol, also showed adequate inactivation of the virus.
WHO-recommended formulations
The disinfectant I recommended by the WHO consists of 80 volume percent ethanol, 1.45 volume percent glycerine, and 0.125 volume percent hydrogen peroxide. Disinfectant II consists of 75 volume percent isopropanol, 1.45 volume percent glycerine, and 0.125 volume percent hydrogen peroxide.
